WATER-PURIFIER.

SPECIFICATION forming part of Letters Patent No. 448,416, dated March 17, 1891.

Application filed October 9, 1890. SerialNo. 367,572. (No model.)

To all whom it may concern: above, and as air is by suitable means forced Be it known that I, VERNON M. DORsEY, a through the staging it will be seen that the citizen of the United States, residing at Cashoxidation of the impurities in the water will ington, in the District of Columbia, have intake place, as will be hereinafter more fully 5 vented certain new and useful Improvements described. A dam d is placed between the in Purifiers; and I do declare the following forward ends of the platesD D, and has perto be a full, clear, and exact description of the forations d in its upper portion, which, as they invention, such as will enable others skilled form the only outlet for the water from bein the art to which it appertains to make and tween the plates D D, cause the water to 10 use the same, reference being had to the acback up until it reaches a level, Where it can companying drawings, and to the letters of overflow through the said perforations, and reference marked thereon, which form a part they thus cause the water to constantly cover of this specification. the points (1 projecting from the partitions My invention relates to certain new and d and side bars 61 These points are pref- 65 I5 useful improvementsin purifying water ofits erably constructed of some non-corrodible organic impurities by the oxidation thereof metal, such as aluminium, and, as shown in caused by spraying the current through a Figs. 2 and 3, should alternate, the lines joincurrent of oxygen (either by itself or mixed ing their points forming a series of re-enwith nitrogen in the form of atmospheric air) tering and salient angles. It will now be 20 and of killing the animalcules contained in evident that if a current of electricity be such water by the passage of an electric curpassed through the wires which are connected rent therethrough; and it consists in the proto the two side bars (1 of the plates D and D cess thereof and in the arrangement, conand to the opposite poles of a source of elecstruction, and combination of the several tricity, the current will pass from the non- 25 parts used for carrying out the said process, oxidizable points (1 projecting from the one as will be hereinaftor more fully described side to the points projecting from the one and claimed. side of one of the nearest partitions, and so Referring to the accompanying drawings, on until the points on the opposite side bar in which corresponding parts are designated are reached, the current jumping from the 0 by corresponding letters, Figure l is a side one set of points to those opposite thereto, elevation of an oxidizer and electric bath 0011- passing through the water to be purified, and structed according to this invention. Fig. 2 in so passing through the water will kill many is a perspective View of one of the bath-pans, of the animalcules contained therein. The a port-ion thereof being broken away. Fig. 3 plates D D are arranged upon the step b of 3 5 is a plan view of the pan shown in Fig. 2, the the frame B, the rear open end of the one pan top thereof being removed. Fig. 4 is a verbeing below the chamfered forward edge (Z tical transverse section on line no a: of Fig. 1. of the plate D upon the next higher step of Two plates D D, of glass or other insulating the frame-work, the upper pan receiving its substance, the one above the other, rest upon supply from a suitable reservoir a, while the 0 40 each of the steps b of the frame-work B, the lower plate D upon the lowest step of the said space between the two plates being divided frame-work drains into a suitable conduit E. into a numberof longitudinal-channels (Z by Oxygen or atmospheric air is also forced by means of the metallic partitions d and side suitable mechanical means through the said bars (1 each of the said partitions and side frame-work, and, passing between the plates 5 5 bars having a binding-screw d by which it D D thereon, comes in contact with the water may be connected to the desired pole of a flowing over the chamfered or serrated edges source of electricity. The lower plate D exd of the said plates D, which will thus he tends farther forward and backward than the broken up in a fine stream, permitting the upper plate D, the rear end of the said lower atmospheric current to reach every portion 50 plate upon one step being under the serrated thereof and to thoroughly oxidize the organic forward edge d of the plate D upon the step impurities contained therein. By makingthe points (1 of aluminium, as above described, the formation of a soluble oxide of low conductive power is prevented and the deteriora-' tion of the water by taking such an oxide into solution is obviated. It will also be obvious that as each of the partitions d is provided with a binding-screw, if desired for any reason to cut off the passage of electricity through any one of the longitudinal channels of the several plates, it may be readily done by making the suitable connections by means of wire to the proper binding-posts.

Having thus described my invention, what I claim as my invention is 1. The combination, with an insulatingplate having a dam upon its lower edge, of side bars upon the side of the said plates, and conducting-points projecting inwardly from the said side bars, the said conducting-points upon the opposite side bars being connected with the opposite poles of a source of electricity, as described.

2. The combination, with an insulatingplate having a chamfered lower edge and a dam above the said edge, of bars upon the side of thesaid plates, and connectingpoints projecting inwardly from the said side bars, the said conducting-points upon the opposite side bars being connected with the opposite poles of a source of electricity, as described.

3. The combination, with two insulatingplates, the one above the other, of a darn at the lower edges of the said plates, bars at the side of the said plates, longitudinal partitions between the said plates, and conductingpoints projecting from the said partitions, and side bars, the said side bars and partitions having binding-posts thereon, as described.

4. The process of purifying water, which consists in passing a current of electricity therethrough and in oxidizing the organic impurities in said Water by causing it to fall over a plate having a chamfered edge, and in passing a current of oxygen through the spray thus formed, as described.

In testimony whereofl affix my signature in presence of two witnesses.
